Some passengers travel on service 99 between silksworth and enterprise park which if service 99 gets withdrawn then passengers can get service 33/33a and service 8, it's been suggested that when morrisons open at trimdon street that morrisons at seaburn will close and earmarked for housing developer with staff transferred to trimdon street, since service 99 gets a lot of passengers from Sunderland north estates to seaburn morrisons then it might spell the end of service 99 unless GNE runs the service from Sunderland to north estates via trimdon street.
